In honor of great YouTube channels everywhere, we're trying to start a movement. But we can't do it without you.

Last week, we unleashed our first #subsaturday (ie, "Subscription Saturday") Tweet and over 400 of you joined us in shouting out the YouTube channels you thought were most deserving of a little extra attention. It generated some enthusiastic comments, made this news update and even poignantly touched one soul. Not bad for our little experiment.

Now we're hungry for more. Please join us this and every Saturday, and Tweet links to 1-4 of the YouTube channels you want the world to know you love. Don't forget to include the #subsaturday hashtag so we can see the full force of our effort and easily discover new channels to watch. Like the #followfriday and #musicmonday before it, we won't rest until #subsaturday is a trending topic on Twitter all day Saturday. Can we do it?
